BICYCLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 564,134, dated July 14,1896.

Application filed January 7, 1895. Serial No. 584,163. (No model.)

To aZZ whom it may concern.-

Be it known that I, DANIEL W. ALBRIGHT, a citizen of the United States,residing at Oedar Rapids, in the county of Linn and State of Iowa, haveinvented certain new and useful Improvements in Bicycle-Supports; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of my invention is to produce a bicycle-support which may beattached to awheel without altering the same and which when attachedwill present a neatappearance.

A further object of my in vention is the production of a support of suchconstruction and arrangement with respect to the bicycle that it may bereadily released by the rider without dis-mounting and which when soreleased will automatically assume its proper position for supportingthe wheel.

In the accompanying drawings, Figure I is a side elevation of a bicyclewith my support attached and in its normal position, the supportingposition of the same being shown in dotted lines. Fig. II is a rearelevation of the bicycle, showing the support swung down to thesupporting position. Fig. III is a side elevation, on an enlarged scale,of the support and mechanism for attaching it to the cycleframe. Fig. IVis a View of the head of the support at right angles to the positionshown in Fig. III. Fig. V is avertical longitudinal. section of Fig. IV.Fig. VI is a section on the line 00 0c of Fig. III. Fig. VII is a detailview of the retaining-hook D and its securing mechanism. Fig. VIII is adetail view of a modified form of the lower ends of the legs of thesupport.

Referring to the letters on the drawings, A indicates the rear brace-rodof the bicycle, extending, as usual, from the upper rear angle of theframe to the rear axle, and B indicates a clamping-collar provided withan ordinary clamping-screw G and longitudinally adj L st-- able upon thebrace-rod A.

The collar B, for a purpose hereinafter apparent, is secured to thebrace-rod in such position as to be substantially in vertical alinementwith the axle of the rear wheel,

and its face upon the opposite side of the frame from the screw G isangled in such manner as to have a plane a parallel to the brace-rod anda second plane I) at a considerable angle, as illustratedin Fig. III,against which is pivotally retained the correspondingly-angled head 0 ofthe support, as by a stud E, revolubly mounted in the collar andprovided with a squared head E. The head E projects beyond the angledface of the collar and enters an inclined-sided aperture in the head 0of the support in order to accommodate a slight rocking or tilting ofthe support-head upon a pintle II, which passes through the head 0 andthe head E of the stud at right angles to the latter.

The purpose of the abutting angled faces of the support head and collaris to enable the support when in the normal position to lie parallelwith and in close proximity to the brace A and to compel it whenreleased and thrown backward to assume a position at a considerableangle to the brace for the purpose of constituting a secure support andto bring the center of gravity of the Wheel a considerable distance toone sideof the wheel.

The angled face of the support-head is produced by simply beveling itsextremity beyond the pintle H, so that in either position of the supportthe side of the head parallel to the supporting-legs lies flat againstone of the planes of the angled face of the collar and the direction ofthe support in consequence depends upon the plane against which the headbelow the bevel abuts. Not only is this cam action efficient inautomatically directing the position of the legs with respect to thewheel, but it also constitutes a locking device, inasmuch as the head 0must have slight lateral movement during the reversal of the support. Itis to accommodate this movement that the pintle connection between thestud and the support-head is employed, the parts being made sufficientlyloose to acmodate this slight yielding action, but not to such a degreeas to overcome all resistance.

The support may be made of a single rod, but I prefer to employ theconstruction shown in the drawings, in which a leg 0 is hinged, as by apintle I, within a recess in the head 0, from which latter extends arigid leg 0. p

The legs 0 and G are preferably made semicylindrical and are provided intheir adjacent faces with corresponding longitudinal recesses 0 withinone of which is terminally secured a leaf-sprin g F, the tendency ofwhich is to force the legs apart, but which, when they are heldtogether, as by the clip-hook D,is entirely concealed. Theclip-hook Dreferred to is adjustable by means of a split collar and clamping-screwG upon the brace A, and consists of a leaf-spring forming asubstantially cylindrical portion and a clip end. The hook is preferablylocated at the upper extremity of the brace A, and constitutes lockingand releasing mechanism for the support immediately under the seat ofthe bicycle within easy reach of the rider.

By the construction hereinbefore described I am enabled to produce asupport for bicycles which is normally carried close against the rearbrace of a bicycle and which when released by the rider by forcing itsend from the hook I) automatically assumes a position at a considerableangle with respect to the wheel and which by the same act isautomatically converted into a two-legged supporting-frame.

The purpose of the location of the supporting-collar in verticalalinenlent with the rear axle is to locate it in alinement with thepoint from which the wheel swings in the event of the front wheel beingturned by accident or design and thus reducing to the minimum theliability of overthrowing the bicycle in the event of its being jostled.

I do not desire to limit myself to the details of construction hereinshown and described, but reserve to myself the right to vary and modifythe same at will within the scope of my invention.

hat I claim isspect to the stud pivotally securing the support to thesquared head of the stud, substantially as specified.

2. In a support for bicycles, the combination with a supporting-collar,of a support pivoted thereto, said collar having two separate anddistinct faces upon the opposite sides of the pivot and at an angle withrespect to each other, the line of juncture of the faces extendingentirely across the collar and diametrical with respect to the pivot,and said support pivoted to the supporting-collar being provided with anangled face corresponding to and adapted to cooperate with thesupporting-collar, substantially as set forth.

3. In a support for bicycles, the combination with a supporting-collarhaving two. separate and distinct faces and at an angle to each other,of a revoluble stud projecting from the collar and provided with asquared end, a support provided with an angle end, and with a square,inclined-sided aperture, and a pintle passing transversely through thesupport and the squared head of the stud, sub stantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL XV. ALBRIGHT.
